(Avadh)2010-06-112010-06-1120080031-9007https://hdl.handle.net/2445/12856We study the influence of elastic anisotropy on nanoscale precursor textures that exist in some shape-memory alloys and show that tweed occurs in the limit of high elastic anisotropy while a nanocluster phase-separated state occurs for values of anisotropy inhibiting the formation of martensite. These results are consistent with specific heat data, elastic constant measurements, and zero-field cooling or field cooling experiments in nonstoichiometric NiTi alloys.4 p.application/pdfeng(c) American Physical Society, 2008Materials nanoestructuratsAnisotropiaCristal·lografiaNanostructured materialsAnisotropyCrystallographyinfo:eu-repo/semantics/article559574info:eu-repo/semantics/openAccess
